WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 244,505, dated July 19, 1881.

Application filed November 26, 180. (No model.) I

To all whom it may concern:

Be it known that I, HENRY T. WEsT, of New York, in the county of New York, in the State of New York, have invented a new and useful Improvement in Wagon-Jacks, of which the following is a specification.

My invention is a wagon-jack of construction as fully described hereinafter, so that it may be cheaply made, readily applied to raise vehicles of different heights, and easily operated and secured in position without the use of special retaining devices.

In the drawings, Figure 1 represents a side elevation of my improved jack. Fig. 2 is a V sectional elevation of the same; and Fig. 3, a transverse section taken on the line 1 2, Fig. 1.

A represents the base of the jack, which Between these brackets is pivoted a lever, B, having a cross-head, B, thepivot b passing through said head into elongated slots 0 c of the brackets a a. Suitable washers a may be arranged on the pivot 1), between the lever and the brackets, to limit the side play of the lever.

0 represents a bar, which extends between the brackets to at, its lower end resting on the cam-like head 13 of the lever B. A lug, 6, projects from one side of the bar into an elongated slot, 6, of the bracket a, thus guiding and steadyin g the bar when the latter is raised or lowered. The bar is also guided and held in bar, so that upon tilting the block and applysecurely in place without any screws or clampin g devices.

It will be noted that the cross-head bears upon the face 00 between the brackets, so that there is no strain on the pivot e which slides in slots.

I claim- 1. In a wagon-jack, the combination, with a bar, of a sliding block provided with interior projections arranged to bite into the bar when weight is applied to the block to tilt the same, substantially as set forth. Y

2. In a wagon-jack, the combination, with a bar sliding between brackets and block adj ustable thereon, of a lever with a head extending at both sides at right angles thereto, pivoted to a sliding pin and arranged and operating and bearing upon a face, w,between said brackets, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
